The word "tiara" refers to a high crown, richly ornamented. Tiaras are traditionally worn by women for very formal occasions or social gatherings. However, Wonder Woman wore hers and used it as a weapon as well.
Let this tiara represent the princess or queen that you are, the rich life you lead and remember...don't let anyone stand in your way (otherwise you may have to take the tiara off and use it as a weapon).
